SNAP-HOOK.

SPECIFICATION forming part of Letters Patent No,'384,992, dated June 26, 1888.

Application filed Apiil 20, '1888.

T0 aZZ whom, it may concern,.-

Beit known that I, HENRY MePnERsoN, a citizen of the United States of America, residing at Troy, in the county of Rensselaer and State of New York, haveinvented certain new and useful `Improvements in Snap-Hooks,\of which the following is a specification, reference being had therein to the accompanying drawings. y

My inventionrelates to certain improve ments insnap hooks, such as may be employed to connect various parts of a harness, and for any other purpose where itkis necessary to have an easy means for connecting and disconnecting parts; and the objects of my improvement are to produce a simple and inexpensive snap-hook having a latch pivoted to the frame thereof and a spring located within the segmental `cavity of said frame. I attain these objects by the constructionillustrated in the accompanying drawings, in which- Figure l is a side View of a snap-hook constructed in accordance with `my invention. Fig. 2 is a top View of thesame. Fig. 3 is a longitudinal section of the same. Fig. 4 is a longitudinal section of t-he frame with the spring retaining-lip turned up to prevent the necessity of coring the cavity in the frame. Fig. 5 is a perspective view of the latch.

In said drawings,A represents the frame or body, having at one end the hook A'l and at the other end a ring, A, that may either be ilattened to receive a leatherstrap, or circular, as shown, to receive a link cfa chain. YVithin the body A is formed a semicircular cavity, a, having two dat side walls, a, integral with said body,to receive the segmental inner portion of the latch B and the spring C; The latch is connected to the body A by means of a pivot-pin or rivet, d, passing therethrough. To dispense with the use of a core to produce the cavity a and permit the body A to be withdrawn from the sand,said body is formed with a standing lip, ai, at one end of said cavity,as shown in Fig. 4, and while said lip is standing up it permits the insertion of the spring in the cavity made therefor, even after the latch has been riveted to the body A, and after the spring has been inserted said lip can serial No. 271,215. is@ model.)

be bent down, as shown in Fig. 3. Said lip forms then not only a closure for the spring, but an abutment `for the upper rear angle, b,

tongue b2 of the latch from passing outwardly beyond the point of the hook A?. As before stated, the outer end of the spri ng bears against the bentdownlip ai; but the opposite end ofl said springbears against a radial shouldergbi. formed upon the under side of the latch; and

Aadjaeent to its hoolnfor the under side of the tongue b2 to abut against when said tongue has been sufiiciently depressed to admit anordinary-sized ring of a chain or of a part of a harness. 4

Although I prefer a coiled spring, as shownY at C, as the chamber for its reception can be oflaige size, a flat spring maybe used for the i, same purpose by having one of its ends abutting against the lip a2 and the other against a notch in the radial shoulder b3 of the latch.

Having now fully described my invention, I

claiml. Asnaphook consisting of the body A,

having the semicircular cavity a therein,hav`

said latch between the closure a2 and said shoulder, substantially as and for the purpose described.

In testimony whereof I aiix my signature in presence of two witnesses.
